I received the latest copy of the NASG dispatch and was pleased to find that Peter Vanvliet, NASG webmaster, reported that Lionel had prepared an American Flyer only version of the 2018 catalog. You can access it here. It is in a PDF format.
Now you won't have to waste those precious milliseconds of your time clicking through the 2018 Big Book to see the AF items. And with all that time saved you can get back to those S scale projects on the workbench!
